Opel engine fault light came on for a while, and then went out. What happened?

Opel engine fault light came on for a while and then went out. Reason:

1, the instrument indicates that the gearbox is abnormal or the fault light is on, and the gearbox fault will generally alarm.

2. It may be that the electronic components of the gearbox are out of order. The solution is: use computer to detect and replace damaged electronic components;

3. The mechanical parts of the gearbox are seriously worn, and the solution: repair the damaged mechanical parts;

4. There is also an engine or ABS fault that sends out an error signal and interferes with the gearbox. Solution: Check the engine and ABS, and repair the damaged electrical components.

If the fuel quality is not good, it may also lead to insufficient combustion during driving, and it will jump out of the engine fault light, but it will not last long. If you open it again, it will naturally go out. We don't have to worry about this situation. Probably with inferior gasoline. However, before the gasoline enters the combustion chamber, it is filtered by the gasoline filter, which will not cause any harm to the engine. So there is no need to smoke inferior gasoline. After burning it, you can change to a regular gas station.

In addition, some old cars have a lot of carbon deposits, which can easily lead to engine failure lights, because carbon deposits themselves have adsorption. In case of fire, if the engine fault light lasts for tens of seconds, it will go out because of carbon deposition. Because the car has just started, some of the sprayed fuel will be adsorbed by carbon deposits, and the fuel concentration entering the cylinder is low, which leads to ignition.

Finally, after stepping on the accelerator, the engine fault light came on, but it went out after a while. This situation is due to poor air intake, or the air filter is too dirty and needs to be replaced.
